LUBRICATOR- Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed October 19, 1906. Serial No. 288,490.

To alt whom, it may concern.-

Be it known that I, CHARLES SIGISMOND ZEYEN, a subject of the King of Belgium, residing in J emeppe-sur-Meuse, in the Kingdom of Belgium, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of this invention is to accomplish the continuous introduction of a homogeneous mixture of oil and graphite or other materials into the parts to be lubricated. This result is obtained by a lubricating apparatus comprising two kinds of istons, a principal piston producing at eacli revolution of the machine the stirring up or mixing of the oil contained in the reservoir and one or several other pistons having for their object to drive the oil charged with graphite to the cylinders or to the places to be lubricated.

The accompanymg drawings show by way of example one arrangement of this system.

Figure 1 is a vertical section of the apparatus on the line E F of Fig. 2. Fig. 2 is a horizontal section of the apparatus on the line AB CD ofFig. land K L of Fig. 3. Fig. 3 is a section on the line G H of Fig. 2. Fig. 4 is a section on the line I J of Fig. 2. Fig. 5 represents diagrams of the movements of the piston.

The oil is poured on a sieve 1, whence it falls into the reservoir 2, closed by the cover 3. The sieve is then lifted and the desired quantity of graphite is added. The reservoir is provided with' a sight-hole 4. The bottom of this reservoir is of funnel shape and communicates through the conduit 5 with a hollow cylinder 6, formed in the lower part of the lubricator and in which moves the piston 7.

One or two conduits 8 lead the mixture from the upper part of the funnel to a horizontal conduit 60, with which communicate the suction-conduits of the mixingiston 7 and of the distributing'pistons 1 1. t each oscillation of the driving-lever of the lubricator the piston 7 sucks through the conduit a certain quantity of the mixture contained in the reservoir 2, then returns it into this same reservoir by the conduit 5, thus forcing a vertical jet of oil into the bottom of the reservoir and producing a homogeneous mixture of oil and graphite. There are as .many distributingpistons 11 as the number of parts the lubri- 6o by raising its valve 12 into the conduit 13, 5 5

whence it passes through the tube 14 to the parts to be lubricated.

In the lower part of the lubricator is formed a chamber .15, in which steam may be caused to circulate to maintain the appara- 7o tus at a convenient temperature.

The reciprocating movement of the plunger 7 and pistons 11 is caused by cams 16,

eyed on the shaft 17 and acting in grooves 18 and 19, formed in the ends tons. The length of the groove 19 of the plunger 7 is about equal to the width of the cam 16, so that this plunger 7 follows the movements of the end of this cam. This cam making one oscillation for each oscillation of the driving-lever 22, it results that for each of these osclllations the piston 7 will have traveled a complete course-that is to say, sucked a certain quantity of the mixture from the reservoir 2 by the conduit 60, then returned this same mixture into the reservoir by the conduit 5. The length of the groove 19 is regulated by a screw 20, maintained in position by a lock-nut 21.

If the pistons 11 were driven in the same 0 manner, the quantity of lubricant delivered by the lubricator would be too great, for in practice it is not possible to decrease the diameter of these pistons below a certain limit. For this reason and by a long stroke of the pistons llthe infallibility of workin of the lubricator in s ite of the graphite the parts are arranged so t at the pistons 11 only make a complete stroke forward and backward for a certain number roo of oscillations of the driving-lever 22. This result is obtained in the manner hereinafter described.

The lever 22, operated in any known manner by a rod connected at one end to a reg,

revolving part of the machine and at the other end to the part 23, is not pivoted, as in other lubricators, at a fixed point. It carries at its end a collar-or stra 24, which surrounds an eccentric 25, which turn on a bushing 26. This bushing is fixed to one side of the lubricator. In this part of the said pis- 7 5 so as to assure 5 itself may 1 1o 25 are formed three inclines 27, all pointing in the same direction around the exterior of the eccentric that is to say, in contact with the strap 24. In the bushing 26 are arranged similar inclines 28, but arranged in the opposite direction to those marked 27 and being in contact with the interior of the eccentric. In each of these openings forming the inclines is located a small roller 29 or 30. It is advantageous in order to guide these rollers to place toward the base or wider end of the openings a small spring (not shown in the drawings) surmounted by a piece 50, embracing a part of these cylinders. When the rod connected to the machine draws the lever 22 toward the right, (see Fig. 3,) the strap 24 causes the roller 29 to move up the incline toward the narrow part of the opening. 27, and this roller by friction between the parts 24 and 25 moves this latter. necting-rod moves the lever 22 toward the left, this roller 29 becomes disengaged, and it is the roller 30 which clutches thepart 25 to the bushing 26 and prevents it moving back. Finally under the action of the alter nate movements communicated by the rod connecting the machine to the lever the eccentric 25 will turn in the same direction as the hands of a watch.

Instead of employing the inclines 27 and 28 and rollers 29 and 30 the same effect may be obtained by employing pawls acting upon fixed teeth on the eccentric or other analogous form of construction.

The eccentric 25 and rollers 29 and 30 are held in place by two plates 61 and 62.

In consequence of the rotation of the cocentric the lever 22 receives an oscillating motion around a center movable with respect to the lubricator which may be considered as stationary. In other words, any point of this lever will describe a series of arcs the distances of which will vary from the center of the bushing 26. This lever 22 acts upon the shaft 17 through the medium of a casing 31, keyed upon this shaft and provided with an opening 33, through which passes the lever 22. This lever is provided with an enlargement 32. It is this enlargement 32 which comes into contact with the casing 33' In consequence of the special movement of the lever 22 this point of contact will be, according l)( the position of the eccentric 25, more or less distant from the center of the shaft. In other words, the arm of the driving-lever acting on this shaft will be longer or shorter. As the travel of the connecting-rod acting on the part 23 re mains constant, it results that the extent of the movements of the shaft 17 will vary and that the middle point of each of the oscillations will be displaced during each oscillation.

It has been stated above that the groove When, on the contrary, the conbackward movement of the piston 7 has about the same length as the width of the cam 16, keyed on the shaft. It results from this that the piston receives the same movement as the cam. At each oscillation of the driving-lever it therefore has a complete stroke of slightly-variable length. The groove 18 of the pistons 1 1 on the contrary, is much longer than the wicth of the cam 16. This length is re ulated by means of a screw 34, fixed on t e piston lland maintained in position by the lock-nut 63 and guided by a stufiin -box 35. The length of this groove is such that the cam 16 during the suction of the piston 11, for exam 1e, only bears against a part of this piston (t at is to say, in this caseagainst the screw 34)-at the end of its motion, so as only to advance the said piston a distance equal to a small fraction of the extent of oscillation of the cam 16. At the following oscillation, the midclle point of this oscillat on being passed, the piston will be moved an equal length, and so on until the relative displacement of the oscillations changes direction. From this moment the cam instead of acting on the screw 34 will act in the same manner upon the bottom 36 of the groove 18.

Finally at each oscillation of the lever 22 the piston 11 will receive a small impulse. These impulses first being produced in one and then in the other direction will thus have the efiect of causing a complete stroke of the piston 11 after several oscillations of the lever 22.

If the length of the groove 18 is regulated so that at each oscillatlon of the cam 16 this latter acts alternately upon the ends 36 and 34 of this groove, each of the partial move-' ments of the piston 11 will comprise a forward motion and a backward motion of less extent. This method of regulation enables an exceedingly small quantity of oil tobe driven to the arts to be lubricated at each oscillation of t e lever 22. This movement of the pistons having forward and partial invention.

The various movements of the pistons 7 and 1 1 are represented in the diagrams at Fig. 5, in which on five horizontal lines a b c d e are represented the displacements of a point of the pistons 7 and 11 for five successive os-,

eillations of the lever 22. In the vertical column A are represented the displacements of a point of the piston 7. resented the displacements of a point of t e piston 11 when the len such that at each osci lation of the cam 16 thislatter only touches one of the ends of this groove. In the column C is indicated the displacement of a point of the piston 11 when the length of slot 18 is such that the cam 16 will touch both ends thereof when oscillated.

To render the action of this lubricator easy In column B are re th of the groove 18 is IIL 1s characteristic of this and. prevent it Wearing out, the shaft 17, the cams 16, the istons 11 and 7, and their accessories are coated in an oil-bath contained in the reservoir formed by the sides 37 and the bottom 38 cast in one piece with the body of the lubricator. A. cover 39 covers this reservoir. It is evident that this same lubricator may be utilized for oil mixed with sulfur or any other analogous matter.
